BURNISHING-M'ACHINE.

SPECIFICATION forming part of Letters Patent No. 718,013, dated January 6, 1903. Application filed September 22, 1902. Serial No. 124,275; LNo model.)

To all whom, it may concern:

Be it known that we,W1NEIELD J.M1T0HELL and JAMES R. MITCHELL, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvementsin Burnishing-Machines,of which the following is a specification. I

This invention relates to machines for burnishing boots and shoes, and has particular reference to that type of such machines which employ soft and yielding rotary burnishing elements.

Primarily the object of the invention is to provide a machine of this'character having means for imparting both rotary and reciprocating movements simultaneously to the burnishing element or tool.

Another object of the invention is to provide such a machine as stated with means for heating the rotary elements.

Other objects of the invention will be stated hereinafter.

To the above ends the invention consists in the construction and arrangement of parts substantially as hereinafter described and claimed.

Of the accompanying drawings, Figure 1 represents a plan view of a machine embodying our invention. Fig. 2 represents a section on line 2 2 of Fig. 1.

The same reference characters indicate the same parts in both figures.

The main frame of the machine is represented at a and may be of any well-known or preferred form. That which we have illustrated represents a hollow casting with a suitable flange at the base for attaching the machine to a fixed support and having arms for supporting certain of the bearings, as hereinafter described. A main shaft 1) is shown as mounted in suitable bearings near the lower portion of the frame a, said main shaft having one or more belt-pulleys c for receiving power. The upper end of the frame is provided with bearings for a shaft cl, which we will refer to as the upper shaft. At a slightly-lower point the frame is provided with bearings for a brush-shaft e, and at a still lower point bearings are provided for a shaftf.

Pivotally supported upon the shaft 01 is a rock-frame g, said frame having bearings 71. for a shaft h. The shaft 72 projects at each end from the bearings of the rocking frame, and at one end of said shaft is a heel-bur- -nisher 2' and at the other end a sole-burnisher 7c. The heelburnisher has its periphery curved in cross-section to substantially fit the curves of a French heel, while the burnisher 7c is, as shown, preferably substantially cylindrical in form. The body of each burnisher is made of yielding material, such as felt or rubber, said body-having a covering of cloth provided with a coating of glue and iron filings. This coating, supported by a yielding body, as stated, affords means for imparting a very high and hard-finished gloss or burnish to the heel or sole subjected to the action thereof.

The shaft (1 is rotated by a belt d, connecting a pulley d on the main shaft 1) with a suitable pulley at one end of the shaft d. The shaft c is provided with a circular bristle or hair brush c and said shaft is driven by a belt e from a pulley e on the main shaft 1). The shaftf is driven from a pulley f on the main shaftb by means of a beltf. A belt Z connects suitable pulleys on the shafts cl and h, whereby the burnishing-shaft h receives power from the main shaft.

As has been stated, the frame g is mounted loosely on the upper shaft 6!. The rear portion of said frame is provided with an extension m, having acounterbalance 0, While the front portion of said frame is connected by means of an eccentric-rod q with an eccentric p on the shaftf. The upper end of the eccentricrod q is pivotally connected, as at q, with an arm or bracket depending from the frame g. It will be readily understood that during the operation of the machine the rotation of the shaft fwill cause the frame 9 to be rocked about the axis of the shaft at through the medium of the eccentric and eccentric-rod p and q, respectively. It will also be seen that the two belts cl and Zcause the shaft 71 and the burnishing elements 2' and 7c thereon to rotate. Therefore the burnishers have notonly a rotary movement about their own axes, but they have a reciprocatory movement so far as concerns the work which is held against them. These combined movements avoid the liability of leaving burs on the Work when the latter is separated or removed from the burnishing- I tools.

It has been found desirable in practice to keep the coatings of the bu rnishing elements warm, so as to better polish the work which has been coated with blacking containing wax as one of its ingredients. As shown most clearly in Fig. 1, 9 represents an idler, the huh of which is mounted on a stud-shaft r pivotallv connected with the rocking frame at W. The pivot r comprises a bolt which may be set up so as to hold the idler r in the position in which it is shown in Fig. 2, or it may be loosened to permit the stud-shaft to be swung so as to carry the idler raway from the periphery of the burnisher i. The burnisher 7c is similarly provided with means for heating it, said means comprising an idler s, the hub s of which is mounted on a stud-shaft s pivotally connected with the frame g, as by a bolt 3 The idlers r and s are hollow, as indicated by dotted lines, and they are adapted to be heated by suitable gas-burners at the inner ends of pipes t, which enter the hollow idlers. The pipes t extend backward along the frame g and are or may be provided with suitable nipples t,to which rubber gas-supply pipes may be connected. The burner ends of the pipes 6 preferably extend into the idlers r and sin such manner as to permit the latter to be swung away from the burnishers z and 7c in the manner hereinbefore described Without necessitating any movement of the gas-pipes or burners themselves. that the heating-idlers shall be swung very far away from the bu rnishers in order to separate them to the extent necessary or desirable when the machine is not in use. When the machine is in operation,the rotation of the burnishers z' and It causes the heating-idlers which are then in contact with the rear sides of said burnishers to be revolved by contact with said burnishers, thus evenly applying the heat to the latter. The front portions of the burnishers are entirely unobstructed and free to permit the application thereto of the sole or heel of the boot or shoe which is to be held in the hands of the operator or attendant. The rapid up-and-down movements or reciprocations of the burnishers, coupled with the rotary movements thereof, combine the burnishing effects of the hand-tools and rotary burnishing tools heretofore employed. Moreover, it is impossible for an operator to It is not necessary take the work away from a burnisher during the operation at such a moment as would leave a bur or-distinct line or mark on the work, because the reciprocations of the burnishers are too rapid, coupled with the rapid rotations thereof, to enable such an objectionable mark to be left.

After the work has been subjected to the treatment of the heel-burnishert' and the soleburnisher it may be subjected to the action of the finishing bristle-brush 6 We claim 1. A burnishing-machine comprising'in its construction a shaft having a burnisher thereon, means for rotating said shaft, and means for imparting short lateral vibrations to said shaft and its burnisher in a substantially straight plane, whereby the work may be subjected to combined rotary and reciprocating burnishing actions.

2. A burnishing-machine comprising in its construction a shaft having a cylindrical burnisher at one end, and provided at the other end with a burnisher having a rounded periphery, means for rotating the shaft, and means for imparting short lateral vibrations to said shaft and its burnisher in a substantially straight plane, whereby the work may be subjected to combined rotary and reciprocating burnishing actions.

3. A burnishing-machine comprising a rotary burnisher, an idler mounted for peripheral contact therewith, and means for heating said idler.

4. A burnishing-machine comprising a 1'0- tary burnisher, an idler having apivotal support and adapted to be rotated by contact with the burnisher or to be moved out of contact therewith, and means for heating the idler.

5. A burnishing-machine comprising a pivoted frame, a shaft having a burnisher mounted in said frame, means for rotating the shaft, means for oscillating the frame, an idler carried by said frame and mounted for peripheral contact with the burnisher and means for heating the idler.

In testimony whereof we have affixed our signatures in presence of two witnesses.
